There is strength in numbers.
James Surowiecki, author of “The Wisdom of Crowds,” explained why at a talk Wednesday night in Carroll Hall.
A mix of faculty and students totaling about 70 people attended.
Surowiecki focused on the benefits of collective wisdom, citing examples such as the “Ask the Audience” lifeline option on “Who Wants to be a Millionaire,” in which the audience poll boasts a 91 percent success rate in selecting the correct answer.
“Groups of people can be intelligent, even smarter than the smartest in the group,” Surowiecki said.
“If you can tap into the collective intelligence of a team or organization, you can increase the chance of solving a problem.”
Surowiecki said NASA once launched a website where viewers classified Mars craters after a 30-minute tutorial, and the average result was comparable to that of a geologist with seven or eight years of experience.
But Surowiecki emphasized a distinction between certain crowds.
“The real question, the real key, is what does it take to separate a wise crowd from a foolish one?” Surowiecki said.
